If you weren’t aware, the folks over at Good Old Games have been doing a tremendous service to old school PC gamers, as they routinely offer a huge catalogue of nostalgic PC classics for low prices. While not as robust as Steam’s selection, it’s hard to not browse their titles without drifting deeply into fond memories, and maybe instinctively reaching for your credit card once or twice.

That’s an instinct that just got a lot tougher to ignore, considering that GOG has marked down a huge chunk of their library up to 75% until January 3rd. New deals are promised each day until then, but at the moment almost 500 games are marked down and, while some are modern blockbusters, the real deals are to be found if you’re looking to beef up your classics collection. You can hold your finger to the screen and scroll blindly, and in almost every instance you will randomly stop on an all-time, hall of fame classic that is worthy of the meager investment required. While it’s almost impossible to make a cohesive list of suggestions, for any gamers of a certain age, the number of great games available is almost pornographic, and can almost certainly drive the unprepared veteran gamer to madness trying to sort through them all, while still maintaining any amount of restraint.

I can’t speak highly enough of this sale, and whether you’re a fan of the classics, or a newbie boning up on their gaming history, it’s one of the best deals I’ve seen in some time. Even if you’re tapped from Black Friday sales, considering you can walk in with a $20 bill, and leave with 5 of the best games of all time (in a variety of options), it’s hard to not advise heading over and giving a great site some mush deserved business.
